The small steam plume from Eyjafjallajökull on May 23, 2010, where explosive eruptive activity has ceased for now. The big news over the weekend, at least volcanically, was that Eyjafjallajökull seems to have entered a period of relative quiet. The eruption has died down dramatically, with the last ash explosion occurring two days ago. Since…
